1. Overview of PendoTECH PressureMAT
The PressureMAT is a monitor, alarm, and transmitter system designed for use with Single Use
Pressure Sensors from PendoTECH. It is comprised of the control system box with user interface and
the connectors on the back panel where input and output components can be interfaced. If equipped,
the alarm output function includes a dry contact relay output. The transmitter function delivers an
analog 4 – 20 milliamp output signal corresponding to the pressure reading on the display. There are
numerous applications in biopharmaceutical production processes where the system can be used.
The models are as follows:
* Available in “High Resolution” model with HR suffix
System Components Supplied:

1.1. PressureMAT Instrument
The PressureMAT with its user interface is used to display pressure readings, zero calibrate the
pressure sensor, and to access the program menus to edit the alarm high and low set point values and
other tasks.
The sensor pressure is displayed on the LCD display for each input channel. High and low alarm
pressure set points are entered on the keypad for each channel and if the process pressure goes below
the low setting or above the high setting, the system will go into alarm state. With models with the
relay output, the alarm function includes activation of the dry contact relay output, a flashing
“ALARM>” indication on LCD on the same line as the pressure input channel in the alarm state, and
an audible tone for 30 seconds. When an alarm condition goes away, all indicators automatically go
back to normal (unless the optional alarm latching function is turned on which requires STOP to be
pressed to clear the alarm). The alarm functions are always active for all channels. For the
PressureMAT PLUS models, flow or a scaled analog input value can measure & display other values.
Also available is a single channel model PMAT-S:
The model has a unique remote pressure tare input.

1.2. Instrument Details
1.2.1. Hardware Details
There is no power switch so the system cannot be accidentally turned off. When the wall power
supply is connected to the system and plugged into a wall outlet, the system will turn ON. Instructions
to power down the system without unplugging are in Section 1.2.2 (System Power). The Front and
Back Panels details are as shown:
FRONT PANEL:
Note: If a pressure sensor is not connected or is disconnected during operation of the system,
the pressure reading will drift and eventually go to a value greater than 75psi/5.17 bar and an
alarm condition will occur. The time until the high alarm occurs may vary and this feature
should not be used to control a process due to the time variance. Associated relays will switch
and the analog output will send greater than 20mA.
The Sensor Cable Dust Cover / Zero Simulator for PressureMAT (PDKT-650-298CVR) can be used
to:
1) Maintain a zero pressure when a channel is not in use
2) Protect the pins on the re-usable cable

1.2.2. Software Details
The software interface consists of the keypad (shown below) and the 8 line LCD backlit
display. The program/firmware is stored in memory in the control system and cannot be edited
by users. Only settings in the software menus can be changed. The system does not store any
data unless equipped with optional data logger.
There is no power switch so the system cannot be accidentally turned off. When the wall
power supply is connected to the system and plugged into a wall outlet, the welcome screen
will appear momentarily followed by 2 beeps, then the HOME screen will appear.
Home Screen
When the system is powered on, the following HOME screen appears after the welcome screen
with pressures 1 through 4 shown depending on the model number
(with X.XX bar or XX.X psi as designated):
HOME Screen:

schematics are shown in Section 3. Different models and/or settings may show different number
of digits to the right of the decimal.

Navigation Between Pressure Sensor Input Channels
At the HOME screen, the UP/DOWN arrows are used to change the selected pressure input
channel.
Zero Calibration for Pressure Sensors
1. Select the desired input channel using the UP/DOWN buttons
2. With a pressure sensor connected to the system and EXPOSED ONLY TO
ATMOSPHERIC PRESSURE, press the Tare Button (LEFT ARROW button) on the
keypad
3. The display should read 0.0 psi / 0.00 bar
4. If 0.0 psi / 0.00 bar is not displayed, press the ZERO/TARE button on the keypad again
Note: a minus sign may appear on the display when it reads 0.0 psi / 0.00 bar; this is
normal as the pressure measured by the system may be a value such as -0.001 but
displayed as -0.0 psi / -0.00 bar.
Alarm Function
If any channel has an alarm set, the alarm function includes:
a. The display screen will blink “ALARM>” on the channel with the alarm
b. An audible tone for 30 seconds during the present alarm (it is reset for a new alarm
condition)
c. If present, a dry contact relay associated with that channel will switch (i.e., if wired as
normally CLOSED, it will OPEN; if wired as normally OPEN, it will CLOSE)
When an alarm condition goes away, all indicators automatically go back to normal (unless the
optional alarm latching function is turned on). If a sensor is inadvertently not connected or
becomes accidentally disconnected during a process the pressure reading will drift and
eventually go to a value greater than 75psi/5.17 bar and an alarm condition will occur if the
high alarm set-point is surpassed or in psi when the value goes above the hard-coded limit of
75. The time until the high alarm occurs may vary and this feature should not be used to
control a process due to the time variance. Associated relays will switch and the analog output
will send greater than 20mA.
Program Menu
To access the program menu for a pressure sensor, press the PROG key on the keypad with the
desired input channel selected. The program menu is mainly used for setting of the high and
low alarm set points and alarm detect delay. After pressing the PROG key, the following
screen appears with X indicating selected channel:
Note: the PMAT-S menu selections are truncated due to space limitations on certain screens

At the program menu, the BACK button may be pressed to return to the HOME screen or
SELECT/PROG button pressed with the desired menu selected. The appearance and functions
of the menus are as follows:
Input Viewing
At this screen the UP/DOWN arrows are used to select what value is displayed on the HOME
screen. Press the SELECT/PROG button to select what value appears on the home screen for
the respective channel. The “*” appears next to the current selection for HOME screen
display. In most case this will remain as the Pressure value. PV Signal is the present value of
raw sensor reading. The Service Time is the number of hours the system has been in service.
Pressing the SELECT/PROG button will confirm a change- UNTIL THIS IS DONE, A
SETTING CHANGE IS NOT CONFIRMED. Pressing the HOME or BACK button before
confirming a setting change with the SELECT/PROG button will escape from that program
menu without saving changes made before confirming the entry.
Output Viewing
At this screen the UP/DOWN arrows are used to select what value is displayed on the HOME
screen. Press the SELECT/PROG button to select what value appears on the home screen on
the line under the respective channel. The “*” appears next to the current selection for HOME
screen display. The SP Signal is the milliamp output corresponding to the pressure reading.
Name which by default is blank can be programmed in the in the output programming menu.
Pressing the SELECT/PROG button will confirm a change- UNTIL THIS IS DONE, A
SETTING CHANGE IS NOT CONFIRMED. Pressing the HOME or BACK button before
confirming a setting change with the SELECT/PROG button will escape from that program
menu without saving changes made before confirming the entry.
